Bio:German assassin who attempted to kill Winston Churchill on at least 2 occasions. The first attempt was thwarted by Steel, although the Assassin escaped. The second attempt was 2 years later during Churchill's address to Canadian Parliament, where Steel once again, with the help of the All-Star Squadron, saved Churchill's life. The Black Assassin blew himself up rather than get captured, nearly killing Steel in the process.

Notes:Calls himself "Schwarzer Meuchelmörder" in German; English is "Black Assassin".
